Just want to share my experience of 'best' charging method that can maximize the battery life of my Nexus one.
Firstly, let me introduce my equip:
- Machine: Nexus one
- Rom: FRF91 Stock, Deodexed, rooted, busybox... (Geo411m)
- Kernel: intersectRaven's 2.6.35_AVS-925mV_CFS_20100802_1056.zip
- Control: SetCPU, Interactive: 245-960Mhz when on, and 245-245 when screen off
The key method of obtaining max. battery life is the 'GOLDEN' time from 100% drop down to 99%. Once the battery shows dropping from 100 to 99%, the dropping speed is quite stably fast onwards
So, how to retain 100% longer before dropping to 99%? Below are the steps that really work for me:
1) Charge the phone to green light, some where between 90% and 100% (say: 95%)
2) Disconnect USB charging cable
3) Turn off the phone
4) Connect USB charging cable and charge the phone, it should show orange light
5) Set a timer, remember to *ONLY charge the phone for around 20-25mins*
6) The concept is NOT to charge the phone until you get green light. In order words, you need to charge the phone from 95% for 20-25mins where the light is kept ORANGE with the phone turned off!!!
7) After 20-25mins, disconnect USB cable and power on your nexus phone
8) You are done and the battery should last longer before dropping to 99%
9) Time in step (5) depends, you need to trial-&-error
For my experience, I normally charge the phone before I sleep and disconnect the charger. In the morning when I get up, it usually shows around 95% of battery. Then, I power off the phone and charge it. And then I take breakfast, bla bla bla ~ and after around 20mins, disconnect the charger and go to work. The battery can retain 100% for around 30mins of continuous web browsing, facebooking... and when I reach my office, sometimes, the battery still shows 100% !!!
So, above is my experience of how to maximize the 100% retaining time.
Please feel free to try and share with us whether it really works for you
Great advice.
Personally, I can't really be bothered with going out of my way to be overly concerned about battery life. I don't play games on my phone -- that will change when Angry Birds is released for Android -- nor do I watch movies, and I don't really do too much web browsing. Sometimes I listen to music, but not often.
I can go 12-14 hours of normal use (mostly Twitter and text messaging) and that will put me around 45-50%. I'm never somewhere that I can't charge the phone if I need to; USB at work, regular charge at home, and a charger in the car.
All of these tips and tricks for extending battery life are neat, but why bother?
^ Well looking at your usage, and the plenty charging points, of course you dont care. However, some ppl browse a lot, play games, so every last inch of battery life means something.
I just keep spare batteries in my pockets =D
I will try your golden tips.. then I will write my thoughts.
I thank you for sharing.
Screwing up the battery meter does not get you more battery life, period, and I suspect your shenanigans here is doing that. The battery has a set capacity, it's not going to charge more than that.
The Nexus One and a lot of other modern phones with modern batteries DO NOT trickle charge, they charge to 100% and STOP charging. When the phone drops to a certain limit, it charges more. Repeat as long as it's on the charger. This is why you might see it "drop a few percent" when you pull the charger.
Yea this sounds like a huge placebo effect.
Well I just did this, been off charger for over an hour.. still 100% after over an hour and two reboots.
At 1378mAh right now, didn't get a reading straight after first reboot unfortunately.
I'm also trialing autorun killer. Disabled a free services I don't use.. seemingly increased startup time.
heya,
Don't you mean decreased startup time?
Cheers,
Victor
Yeah, that's what I mean.

How do you figure out your mAh level? Spare parts only shows me mV.

This is placebo. In the OP you even say after it finally drops to 99% it drops fast after that. It's because the phone wasn't at 100% all that time. It was giving you a false reading from messing with the charging pattern.
The best way I've found to charge the phone is to delete the battery stats, turn the phone off, and charge it until it's green. I get a great day of battery life with the phone that way.

Totally agree...I just charge when & where necessary and never worry about it! Don't have the time and it seems to last long enough for me to work & play
I had already discovered this and was looking for a fool proof way but I guess you beat me to it. Happens when you traveling alot. For me, I have gotten over 1500mAh more than once..some times 100% would last me half a day too. So it's worth it, my question is whether or not this is bad for your battery? or long term battery life.

I'm fairly sure that the Milliampere-hour (mAh) is the capacity of the battery (the amount of energy it will store). How can you get "over 1500mAh" on a 1400 mAh battery? None of you are making any sense what so ever. You can't get more energy out of a battery by charging it a specific way. If I gave you a bucket that held 10lbs of sand and you filled it with 8lbs of sand and waited a few minutes then started filling the rest slowly, it wont hold more sand. This is nothing more than a placebo effect. The only way to get more time from a battery is to reduce the amount of consumption. The only way to do that is to use your phone less or make your hardware use the battery less such as undervolting your CPU. I tried for the longest time to explain to people that underclocking your CPU does absolutely nothing. If you're still running at the same voltage you're still consuming the same amount of power.
Stop messing around with the battery and the battery stats.
Could someone please use the phone until it goes off in the evening? What percentage is shown on the batteryicon when it goes off? 20% or what?

Actually it's not a good idea to fully discharge the phone often.

I have been using ultimate juice defender and battery life has doubled with usual usage. Maybe this can be considered as an alternative to longer battery life

Hey guys,
Just got my Epic yesterday.. coming from the G1 with lots of experience loading and tweaking ROMs and dealing with same/similar battery issues.
After unpacking the Epic I used it and let it drain down to zero before recharging it; after a full recharge, I loaded up the 7 screens with widgets and ran a live wallpaper (fish). I didn't really use the phone much at all and the phone went from 100% battery down to zero in the span of only four hours!!! Geeze, you've got to be kidding me - four hours battery life?? WTF????!!
Back to the drawing board: I rooted it and ran SetCPU with some power saving profiles. Removed the live wallpaper and went to stock wallpaper. Set display power off at 30 seconds. Note that 4G remains off since there's no 4G in my area..
Couple of questions:
1. Is there any way to toggle 2G/3G like there was on my old G1? I know that was a power saver.
2. I didn't stop to read all the documentation yet (typical male, I know) but is there any way to wake this thing up from sleep mode besides pressing the power button? I can see that power button breaking for as much use as it's getting from me constantly having to wake this thing up!
3. My brightness setting is set to auto - since the display is usually the biggest drain on these things, is there a recommended manual brightness setting (percentage) that seems to work well for you and saves on battery power?
I'm waiting for the Seideo Extended Battery (just like many of you) and am wondering if I should keep the Epic since I'm on the Sprint 30-day Easy Return program.
Appreciate hearing from everyone!
Chris R.
I don't have 4G where I am. But, I have a all black wallpaper(uses less power) and unrooted. I easily get about 12-18hr out of my phone wit normal use(text, talk, and surfing the net with skyfire). Only thing that really kills my battery are games(Robo Defense can take over 30min to play one game).
Thanks for the reply - situation NOT improving
Thanks for the reply.. unfortunately, the situation is not improving...
I tried setting a Sleep Profile using SetCPU that would under-clock the CPU (using the stock kernel) once the screen dimmed and the phone went into Sleep Mode. Unfortunately, as mentioned in another thread here, the result was that the phone froze and required a battery-pull to reset.
I'm really starting to lose my enthusiasm for this device; as beautiful a display and as responsive a CPU/GPU, all of that doesn't mean much if you don't have good power management built into the firmware. At 6PM this evening I pulled it off the charger at 67% charged, it's now 8:35 PM, only 2.5 hours later and I'm down to 22%. I'm in a decent coverage area and get 2-4 bars of 3G strength so I don't think it's an issue of the radio being the culprit; in-fact if you check the battery stats it reports that that lovely Display is accountable for 78% of the battery usage! So I guess we're paying a hefty price for these 4-inch AMOLED displays!
I read somewhere else that the most recent update (DI07) has caused the battery performance to decrease; since my unit is brand-new it immediately went and installed DI07 shortly after the first boot-up so I have nothing to compare it to.. can anyone comment on that?
Thanks!
Chris R.
I'm sure custom ROMs will put performance / battery life on the top of the list but until then, I use JuiceDefender beta and have seen pretty good results with it. It shuts off data whenever the screen is off and since my screen is off a good amount (only use my phone if I need to check email, call, and / or text, which is rare when I'm at work). Other than that, yes, use black wallpaper, lower brightness to the min. in the OS and browser, and don't leave apps that constantly use 3G open (things like ebuddy, pandora, etc.). 3G really destroys battery life so minimal use of 3G data would maximize battery life. Maybe the devs can figure out a way to get at least one full day of battery life on this phone. I'm hoping that is the case.
As to your post, yes, DI07 has resulted in poorer battery life, for whatever reason. I was definitely getting a few hours more with the older firmware. I would not lose hope yet. As disappointed as you are (and all of us are, I can assure you of that), the devs are really starting to push out nice ROMs already, and in a few weeks to a month, I bet we will see some solid battery life. Hell, even 2.2 should yield much better results. Patience
Thanks for the tip!

DI07 has hurt my battery life substantially. In fact, my battery drains very close to twice as fast now with the update. I don't understand what they did. My phone certainly doesn't seem any faster, my display is dimmer, and battery life sucks. I'm going to have to go back to DG27 so I can use my phone all day. With DI07 it always dies on me by mid afternoon. With DG27 it was still running by 11pm at night without even a battery low warning.
juice defender ftw
also, use advanced task killer with low security settings to kill all the background processes. Set the autokill to when the screen turns off. This keeps everything pretty well managed and helps with battery as well
JUICE DEFENDER BATTERY!!! Saved my phone from flying out of my car window at 10 in the morning........
here is a link to a thread I started.
Sharing my juice defender settings. I also use ultimate juice.
http://forum.ppcgeeks.com/sprint-epic-4g/133933-sharing-my-juice-defender-settings.html
I can get a day and a half (or slightly longer) out of a single charge.
YMMV.
Hope this helps
Advanced task killer + Juice Defender. You could also get some custom roms and Kernals that would help boost it.
But that's your best hope. Keep off 4g, wifi, bluetooth, etc.

Look here- try stopping the DRM service and see if that helps your battery life with D107

Ah, the evils of DRM can strike in unexpected ways...
I wasn't really having a battery problem but I just turned DRM off, so we'll see if battery life improves anyway.
I had a whole long post here that got wiped with the xda disk array failure, so I'll just sum that up here too:
1) Use wi-fi if possible - it REALLY helps
2) 4G does not seem to use the battery any more than 3G, although hunting for 4G does and 4G coverage is not as extensive as 3G even in 4G areas. So it's still best to leave it off if you're moving around.
3) Dim your screen and use a dark, static background. AMOLED screens don't work like LCD's; they use more power the more pixels are lit and the brighter they are.
4) GPS also kills your battery - leave that off unless you need it too.
I think that's it. I get about 18 hours on DI07 (even before trying the DRM thing; maybe I can get to a full day!).
One thing I'm noticing after checking DRM - I've got Google Maps' LocationService popping up about every 10 seconds, and I can't seem to shut it off permanently. (I went into Lattitude and turned that off, not sure what else to do.) That can't be helping... anyone know how to get rid of that?
I'm using juice defender and a constant email junkie, but lite use on other aspects of the phone. It goes off charger at 5:30 am and I'm about 67% at around 3p. It then goes in the car charger on the way home. This has much better battery life than the Pre or the Hero as with both I had to turn off email to get it to last throughout the day.
I don't expect these phones to last days, but I expect any phone that I get to last the business day. I've always been one to charge overnight.
Wifi drains battery more from what I've read.

I've heard the opposite that wifi (as long as it's connected) uses up less battery than 3g/4g. Any of them will suck the battery dry if they're searching, so make sure you have a connection to one of them.
Hi everyone, new to the forum. Just started checking it out when the Epic was released and this is my first post. Anyways, here's my question. My phone's been off the charger for 7 hours and 17 minutes and it is now down to 15%.
Display 79%
Cell standby 7%
Android System 4%
Phone idle 2%
Swype 2%
I've gone into the display settings and I thought I had set everything up optimally. The brightness is always very low. The screen timeout is 15 seconds and the keyboard matches that. I don't know what else I can do to cripple the phone to get the battery to last longer.
I have had wifi on, 4g off, bluetooth off, gps off. Really all I have done this afternoon while watching NFL games is check my yahoo fantasy score, play 2 games of WordFeud, and check twitter and facebook. I purchased Juice Defender a week ago and it has been running all day.
Any suggestions for how I can reduce the drain from the display? My background is a black and white picture of a friend of mine, which I thought would help.
Don't get me wrong, I love this phone. But the battery life I've seen is just terrible. I'd love to buy the extended battery from Seidio whenever its available, at least that would make it last longer even if the settings aren't tweaked.
Do you have juice defender installed?
Yep. Its installed and running now.

There are only two reasons for your display to be using that much battery:
a) it's too bright, or
b) you're using it a lot.
If you're using the phone a lot, your battery's going to run out pretty quick and there's no way around that. If you're using it a "normal" amount, which to me means maybe an hour *total* per day of having the display on, then the other culprit is going to be your brightness. (Some would argue that's less than a normal amount, but think about it... you get a new phone, you're going to play with it for a week or two until you've seen all the cool stuff. But at some point you're going to start putting it away most of the time and just using it when someone calls you, you get a message/email or maybe to play a game or two while waiting for the train.)
Set your brightness *all* the way down, just as a test for a couple days. Make sure all the "power saving" features of the display are turned *off* (auto brightness, and whatever that "picture detection" feature's called, I can't remember). You just want the display as dim as possible all the time, just to see what happens. See what the battery usage says after a day or two of this.
My bet is that you'll see a drop, and then as you get into a more normal usage pattern it'll drop further still. You can raise the brightness a couple ticks then as you learn how to stretch your battery out.
Personally, my display is rarely over 15% or so of my usage. Today it's 29%, but it's a Sunday and I don't have anything better to do but play around on my phone.
btw, it's still the first day I've tried this but that DRM thing might be working. It's almost 9PM and I'm still on like 80% battery, and like I said I have been using the phone off and on throughout the day.
That has helped tremendously. I installed it pretty much when I got the phone and I'm able to last the whole work day with 67% left. (10 hour day)
Hi, I been having the HTC Surround for a little over a week now. I love the look and feel to it (I know OS wise it has a lot of improvements to do but I'm willing to put up with it for a bit, considering its a new OS). However one thing I notice is that it has horrible battery life! The phone last about 10/12 Hrs on a full charge. During this time period, there is no heavy use; tops 50 txt messages send and received, about an hour of music, screen lock (brightness set to low, when on), perhaps 15 minutes of talk time, data connection turn off, about 20 minutes of WiFi (I turn off WiFi when not in use), rest of the time on stand by as mention before (with the screen locked). Another thing i noticed yesterday night was that my phone was charge completely, i left it on stand by and within 5 hrs that i slept the phone had gone a little lower than 3/4ths (data connection was off).
I read a post here that said battery may drain quicker when phone is left in cold weather and i thought maybe this could be the case. However I'm really skeptical because i live in Los Angeles. Cold weather, which is this time of the year, is mid 40 degrees at its lowest! That's not cold! But anyways i guess I'll try putting that theory on a test (imma try keeping it warm, see if it makes a difference)
so is anyone else experiencing horrible battery life? Or am I just an unlucky person who got a defective battery?
THANKS in advance

What "theme" are you using?
If I don't use my phone, it will last for days. Even when I use it through out the day, it lasts well into the next morning/afternoon.
The battery life does get better the more you drain/charge it.

well, I been having it for a week now. I seen no difference in battery life. But imma give it another week or so. See if this works. Then I'm gonna try buying different battery. If that doesn't help, I think I'm going to have to switch back to my Samsung Captivate. I would hate doing this, but this type of battery life is a deal breaker. Today, it was even worse! It lasted me only 9hrs while I was at work, which at least 8 of those hrs it was on stand by!
Sounds like you have a bad battery, bro. I'd get it replaced at the store you bought it from.

yeah, I'm going to try this on my day off which is on Monday. Also gives me time to test out the other persons suggestion
thanks for your opinions. I'll get back to you guys and see what happens.
My surround - now two weeks old is showing much improved battery life. It didn't make it through a day when I first got it. Part of that was due to my fiddling with it and part due - I think - to the battery conditioning.
Now, it is going a full day on a charge. I am also switching off 3G and on WiFi when I am in my office or home. It is a bit of a pain in the butt and I hope that M$ gives up some APIs soon so that someone - cough Bruce Jackson cough - will write an app. We'll see.
I have noticed that the Bluetooth drains the battery considerably faster. Try turning Bluetooth off when you don't need it.

I don't use the Bluetooth at all. So this can't be the problem. but thanks anyways. (I might need this information since I was planing on using one in the near future).
So I notice that now, my Surround does get better battery life. (which is absolutely crazy! since now I have the screen brightness on medium and data turn on lol). I guess the battery just needed to be use and charge a bit more. However, I still think battery life could be improved. (hopefully, future updates will teak some system settings that will do this)
I have also decided that I will keep my Surround instead of going back to my Captivate I wish battery life would be better and the OS to be more "open" but truth be told, I fell in love with my phone haha Then when i went back to my Samsung Captivate, it felt weird. Android felt much slower.
So i gave it a little test; I launched messaging, email, music, browser, etc on both phones at the same time. Turns out both of them launch these native applications in the same amount of time.
I guess what makes WP7 fell smother and faster is the (eyecandy) transitions.
think its the battery
ya i have had mine for 2 weeks now and i think the problem is the fact that the battery is a 1230mAh, and we also have a samsung focus with a 1450mAh battery that will last an exra 2-3 hours longer which makes a huge difference! im hoping htc will make a larger mAh battery avaliable, mine will only last anywhere from 5-7 hours from normal use
I just ordered a Mugen 1300mah battery..not *much* more capacity, but hopefully it helps a bit!
if i dont use my surround (like not using too much 3g, wifi, music, gaming, and just normal phone calls and texts) it can last a whole day and probably a lil more, but when i do too much 3g/wifi/gaming/music it drains quickkkkkk.
and i do hope htc will have a larger capacity battery for the surround soon... 1230 is kinda small compare to other phones nowadays..
but still this has much better battery life than my previous phones (diamond2 and touchpro)
i just find myself carrying the usb cable and wall charger alot in my bag :]
and having a car charger is a plus also.
My girlfreind has had the phone since xmas. Initially the battery would lose its charge very quickly. I had her do a bump charge and just let the battery settle in. She can now go up a third day wothout the need for a charge with moderate txt.
Be aware the quick drop whenn taking it off the charger is NORMAL. Read this thread for a discussion of that http://forum.xda-developers.com/showthread.php?t=871051

Agree - Bad Battery Life - But not as bad as some....
Smart phones, in general, aren't what I would call great at conserving battery life under any condition. Pick any model of high-end smart phone and tell me who can get more than 2 days (using every trick in the book to eliminate unnecessary drain). Yes, this phone is under-powered in terms of only having a 1300 mAh battery when it should have a 1400 or 1500.
Cut the unnecessary stuff when you are not using it - Bluetooth, WiFi, etc.
You can easily get a day + out of this phone with moderate/mixed use (some talking, some browsing, some multi-media viewing). That's pretty good, I'd say (from my relative experience across many different types of smart phones). I just plug it in every night.....pick it up in the morning and go. Haven't had any issues with it running out during the day.
Now, if you are starting first thing in the morning and running movies, have the bluetooth going, the WiFi on........well, heck yes, you are going to have a battery drain problem. If you want to run it that way.....just leave it plugged in.
Has anyone used a Seidio Innocell 1300mAh Replacement battery? Was wondering if it was worth the investment to improve the Surround's poor battery performance.
Thanks,
So...when is someone gonna step up to the plate and improve battery technology? It really sucks that these phone manufacturers are giving us ALL these fancy features that drain the battery and when we complain about having poor battery life they are telling us to not use all those fancy features...kinda defeats the purpose of buying a smartphone, am I right?
guys .. wake PLZ UP ))
1 ghz (1-2 core cpu ) ..
3.8 and more screen ..
DEDICATED GRAPHICS .
OS .
with DIRECTX9 Interface .
and that all spiced up with 1600 ma battery in best case .
and that you wana to run more then 6 hours on full load ? say THX TO MS .. for NON multitask os .. overwise battery life was even more lol then this

My surround - now two weeks old is showing much improved battery life. It didn't make it through a day when I first got it. Part of that was due to my fiddling with it and part due - I think - to the battery conditioning.
Now, it is going a full day on a charge. I am also switching off 3G and on WiFi when I am in my office or home. It is a bit of a pain in the butt and I hope that M$ gives up some APIs soon so that someone - cough Bruce Jackson cough - will write an app. We'll see.

I noticed this as well. As time went by the battery actually started to last longer. When i first got it i used it less than i do now and the battery would die before i even got home for work. Now it lasts till about an hour or so after i finish and get home.
does the surround use the same battery as the HTC desire HD?
Theres an ebay seller that is selling a surround battery and wall charger but the wall charger has a sticker that says: For HTC Desire HD
I don't know if it's my imagination, but since the 2.4.6 update, my battery life has dropped a bit. By the time I get into my office from my morning commute, I'm anywhere in the 65-70% battery life after unplugging from a full charge. I haven't done anything new. I always unplug around 8:30 am when I head out, I do some light chatting with gf, browse some sites, check facebook (usually very briefly), and maybe sometimes do a little reading on my device. By the time I get into the office around 9:30 or 10 AM, I'm usually around the 80-85% area with battery.
Lately, doing the same thing, I'm seeing the aforementioned 65-70%.
Is anyone else experiencing decreased battery life since 2.3.6?
I'm on a Tmobile Nexus S, running stock 2.3.6 (no custom ROMs).
2.4.6 ? .... maybe 2.3.6 ... and yes, I also noticed a slight increase in power consuption after the upgrade. The stand-by is still great .. about 0.8 - 1% per hour.
Sorry, yes I meant 2.3.6.
Thanks for replying Ro_explorer. Is your increased power consumption significant? Seeing 65-70% when I'm used to seeing 80-85% as I get into my office, I find, is a large change. To be frank, the battery life of the Nexus S in general isn't so fantastic to begin with... this hit makes it worse.
Anyone else?
I used to get home with about 40-50% after a whole "normal day" (unplugged at 8AM, and getting back home at ~8PM) .. now (with the same average usage) I'm getting home with ~30-40% ... that why I said "slight increase" ...
Not your imagination, I too have noticed this. I hope the next update, will fix this - as I used to get pretty good battery life (even with over 250 apps).
When I recently updated to the 2.3.6, it caused a bug of continuous reboot (every 1-3 minutes), so I had to do a hard reset - now it works fine, but I only have added back about 15 apps - and the battery life sux!
Downgrade OS' it will be ok.
This is so weird. Why is the battery life worse?

You want bad battery life? Try an Evo 4g with a Sense rom. I averaged about 6hrs using a 1500mAh battery, in stock form.
The nexus is pretty light on power consumption, if you ask me. I average 15hrs on the stock 2.3.7 rom/kernel combo, with stock battery.

I'm on 2.3.6 and need to charge every two days. I text a lot and do light gaming. I'm typing this from my phone. Maybe you could drain the battery and wipe battery stats? I'm not even at 50% yet and I charged yesterday.
Sent from my Nexus S using Tapatalk
I also noticed that the battery last less time
I've been waiting to see if anybody else reporting this issue
i noticed a decent increase in battery life going to 2.3.7 and thought that previously the battery life had been fairly poor :\
I am non rooted, and get around 20 hrs on light to moderate use. Again. Stock, non rooted.
How do I recalibrate my battery? I wonder if it could be that...
There are many was to recalibrate. Some involve wiping batt stats, some plugging and unplugging phone several times after charge.
I have always found that using the battery almost all the way down, but not past 5%, and then full recharge conditions it very well.
Oh I've been here to solve the problem
"Why last 2 weeks my Nexus s drain battery so fast ? or I have to calibrate it"
Thank for your notice about update OS to 2.3.6.
I think that's a root cause for me too.
1. Could I rollback to 2.3.4 ,how?
2. Does battery calibration is useful for this case , how?( someone suggest to calibrate when flashing new rom )
Thank you very much..
i want to know who have some methods to do with this stuff

Whenever switching roms, kernels, or batteries, i always perform the following :
1. Charge to a true 100% (Battery Monitor Widget will register +0 to +2 mA)
2. Wipe battery stats using recovery (Amon RA has this option for the Evo, not sure about cwm), Battery Monitor Widget, or a dedicated app.
3. Discharge battery to 0% with normal usage. When the phone shuts down, I pull and re-install the battery and power back up (it will shutdown again very quickly).
4. Recharge battery and be on my merry way.

I found one workaround solution for this issue on
ww.google.com/support/forum/p/Google+Mobile/thread?tid=1684c50cea15282a&hl=en&fid=1684c50cea15282a0004af022e5ed212
Sproogle77 's solution
Problem solved. Using the OS Monitor app, I found that the main culprit was Google Services - the Contacts sync specifically. Even though I had this disabled (only Gmail was being allowed to sync) it was constantly working, apparently trying to fix a location. The message log showed that it was generating continuous debug messages, all about locations - around 10 of these every second.
I have solved the problem by disabling 'Use wireless networks' under the Locations & Security settings.'Use GPS satellites' is still running. This immediately dropped my CPU usage - which had been running around 30 to 40% even when otherwise idle, to around 10%. Google contacts sync is now using 0% of the CPU. The difference in battery life was pretty much immediate and is now back to what it was before - the change in the slope on the battery usage graph is remarkable!
This doesn't really seem like a solution to me, and I don't know whether other aspects of my functionality are being affected, but at least my phone is properly useable again.
I'm testing for 1 day and I think that's working for me.

One reason is that the new version of the stock kernel removed a speed stepping, so it'll power to higher levels faster, thus using more battery.

That actually isn't the problem. I'm using netarchy's kernel and still get this problem.
My battery life dropped from 16 hours --> 6 hours. the slope on my battery usage life is horrible the system is also awake almost constantly even when I'm not touching it / getting no messages.
I will try the fix suggested on the google support forum and see if that does the trick. sloppy update.
I read so many threads and comments complaining about "battery life"
Turning this off and that off, not using this app or that app. Dreaded enemy "wake locks". Turning brightness down and generally Not using all these great devices have to offer to squeeze out more battery life. Even to the extent of over 24 hours.
We have a phenomenal and powerful device that does a whole lot with a huge screen and a ton of great BG apps updating all kinds of information we enjoy these devices for.
MOST of all we all have the (getting rare) opportunity to swap out an inexpensive battery in less than 30 seconds be up and running for another 5-10 hours depending on our enjoyment and use.
Do people not have electricity? They cannot charge every night? They can afford a $600 phone (or $300 subsidized) and $600 plus a year for service but cannot buy a $20 battery in order to actually USE the device as designed and go through all kinds of contortions, apps, settings, and worse, anguish at running out of juice after (gasp) 8 hours?
People getting hung up on "benchmarking" and posting screen shots of phones on battery for 3 days...(of course rarely used) to squeeze and extra 30 minutes.
TURN IT OFF!! bet the battery lasts well over a month. You win!
I guess I just don't understand the "issue" with a device where batteries can be swapped out so easily.
I get maybe 10 hours normally with everything on and at minimum updating. I have infinite screen on and turn it off when I am done using it. (hate those timeouts while reading something). FB and news updates at minimum. Maps always running latitude. If its there its on BT, Screen rotation, GPS, I just don't worry about battery life as I would rather carry an extra battery in my desk at home auto or work and in my wallet than not USE the device as designed.
Personally I would never buy another phone without the ability to swap out a battery lest I would gain have to "ration" my use of such a great device which would be akin to a witnessing a gay man win a date with a single and seductive Angela Jolie . Why bother?
Am I alone here? Anyone else consider battery life as much a non issue as I do on these Samsung phones?
I'm with you on this one. Why do all of that stupid things if you can solve it with $20 battery.

A lot of the battery life threads are related to abnormally high battery drain.
As an example, on GB I would about 1% battery per hour if the phone was idle.
When I upgraded to LPY, I was losing 2-3% per hour, and sometimes higher, because the phone was not going into deep sleep.
This might not seem much of a difference for just 1 hour, but over the course of a day, it is a huge difference.
Now I'm on LPF, my battery drain is about the same, or lower than GB when idle.

I guess "abnormally high" is debatable. For me it would be a 80% battery crapping out before then end of a 2 hour movie.
A day is only 24 hours long and I assume people will sleep for 6-8 hours so Even a 5% drain per hour would mean more than 16 hours of standby with 20% remaining!! How can that be an issue? I doubt my phone "deep sleeps" I have BG apps running all the time with notifications. One extra battery solves all issues. No need for special apps, tweaking this and that, flashing this and that simply for battery life.
If people sleep 6-8 hours during a 24 hour period they can easily and consistently charge their batteries. A 3% drain per hour would not be an issue. If we watch movies and play games we already know the battery will drain within a few hours. Pop in another battery and brand new again.
You are assuming that people are always near a power source.
I am normally near a power source. I am either at work and charge via USB or in my car or at home.
The issue is the past 3 days I was out and about (malls, hotels, restaurants and so on) and was not near a power source for more than 10 minutes. My battery died in about 4 hours of usage. Mostly checking email, instagram and facebook.
I keep my brightness at full strength by the way (unless if the lights are off in bed).
Yes, so battery is an issue.
Not everyone is constantly near a power source.
So you think if I put my fully charged Note into Airplane mode when I go to sleep and wake up in the morning just to find out to my surprise that I lost 32 % of battery life in six hours is normal? In airplane mode? On official update via Kies, never rooted, never anything custom? That is normal to you? Wow, you are either stupid or work for Samsung. If you work for Samsung can you help me to get my GB battery life back? I have already spend good money for the phone, I am not willing to spend a dime extra for another battery on 6 months old phone.
If your phone is working as intended, battery life issues are not really an issue.
It basically means your phone sleeps when its supposed to.
However, some devices never go into deep sleep due to some issue with kernel or a rogue app. Thats where the battery problem comes in.

Thats not normal.
I turn off data and wifi on my Note when I go to sleep (6 hours also) and I loose about 5 to 10 %.
This is with telephone signal only. No data or wifi.
to the post #7. So how come it didn't happened in stock GB previously? In GB I lost about 1 % overnight when in airplane mode. Reliability of batteries on this phone is a big deal, unfortunatelly.
Battery is always an issue. Nobody likes running to the charger every 3 hours. They want to charge and preferably when we are not using it, when we sleep.
So yes, it does not comply with expectatoin with continuous use. So yes its an issue. At least for me
Next to this having the enduser juggle with what wakelocks are or other battery eaters are dont help much. That counts for all smart phones.

There is also the issue about well behaved v badly behaved apps. I've installed apps and my battery life has plummeted, normally due to the app writing tons to the system log as it doesn't run well on my device.
In that situation it's nice to know the phone generally isn't sucking masses of juice itself so you aren't caught out and about with no battery left.
As the OP says, I guess I could carry a spare battery, but I could also carry a spare phone (my old Nokia 6310 used to last weeks on a charge) - and I don't want to do either. I want the battery on my phone to survive general use and still be able to be used for calls if needed. For me, it's not about €20\$20 for a battery, it's about the hassle of having to carry another thing around with me all the time and make sure I'd remembered to charge the damned thing when I actually needed it.
Personally, I use my phone like a tablet and as a phone and generally get 1-2 days out of it no problem. That said there are definitely some battery drain issues with the official German ICS build and it's worth protecting yourself against unnecessary drain if possible.

I happen to believe it's asking far to much of a device once used only as a phone and now as a notebook computer, music player, movie player,gaming platform, big screen, GPS, on and on to be able to operate without expecting batteries to wither within hours. I bought extra batteries so I can use all the functions without worry. There are performance issues people strive to enhance. I get that. But battery life is counter productive to enhancing performance.
I cannot understand all the teeth gnashing about battery life with all the options available Especially those of us who are power users. . not the least being charging while asleep. So many post battery loss while sleeping...... That's what chargers are for.

Sometimes. I go to music festivals where we camp for up to 5 days at a time. I may have access to a powerpoint for 30 mins a day, but not always. I carry spare batteries, but that doesn't mean I want my phone sucking my battery like crazy.
When travelling around, I use my phone more often than normal (gmaps etc)... If I'm away from the hotel for 12 hours +, again, having decent battery life is not an unreasonable thing to want.
My Desire HD (yes I know, smaller screen, slower cpu), could pull over 30 hours out of a battery with conservative use (without turning the radios off).
I still wouldn't give up my Note, but having to recharge each time I get home is pretty annoying.
Ha, ha!
I find it funny that a post complaining about people complaining about battery life ends up with people's comments complaining about battery life!
Seriously, though, when those rogue apps steal my precious battery, I get annoyed. I paid for the damned thing, and I want to use it when I want to use it, not find it is half-drained.
I use it pretty normally, and charge it every day (new batteries are cheap). I carry a spare in my wallet too.
I sometimes spend four hours a working day on the phone, BT all day, plus an hour or two screen and WiFi on. If I have managed it OK (by killing battery stealing apps) I get about 50 to 60% left. If not, I can be down to 30% after that. That may not be enough for the rest of the day.
Why should it be a problem that people like to get a full day from one battery? It is not difficult, although you do need Root. Shame on Samsung that it is necessary, when it is clearly possible.

Lol I was seeking those who don't have issues. And was hoping for a discussion on how they deal with battery life without rationing or tweaking....not more complainers
It's a problem of unrealistic expectations.IMO When you look at the device it self and what it's capable of.
Yeah Samsung could have put a larger battery and fatter back on the phone but people would complain about that. Those solutions are available for power users as well. I think we are lucky to have a device where we have options to solve a basic issue other than not using functions. Apple and HTC do not have the same luxury.
Got to go........ battery is di
I'm a light user with the occasional call and sms and my battery last ~6 days. Phone is 3 moths old. However, I find that my battery usage is very dependent on signal strength. I usually get 4 bars and when that happens battery drains like 10% a day and when it is down to 1-2 bars then it can be 3 times that. I guess I'm fortunate that I get 4 bars most of the time in the office and at home.
I have a battery monitor widget installed and I must say that it makes me paranoid of using the phone and causing high drain. May uninstall it soon and use the phone as it should be used.
My expectations are pretty much met when it comes to battery life of the Galaxy Note. It lasts a whole working day. That's all I need. And for exceptional situations when I don't have access to a socket I have got a spare battery.
It's clear that the Note drains the battery really fast if it's in use. Just look at the screen . I also agree that it's annoying if the battery is empty after only 1/2 working day. But some people really have to blame themselves. If you don't turn off Wifi, Bluetooth and GPS when they are not needed it's no miracle that the battery is empty in no time. If you constantly check Facebook, Twitter and the like you have to accept that battery life will be significantly shorter.
For me the worst things are Bluetooth headsets. Not only is it annoying to have one more device that has to be charged but it also constantly drains the battery of the phone. Ok those wireless headsets are comfortable but you pay for it by faster battery drain.
hi guys, cool down.
the different opinions about the battery issue are resulting from the different way of using the phone along with the life style.
Some may need a bckp bat. Some can make sure they are always close to a power source ( if people spend a substantial part of the day in cars f.e.) Some even need an additional external power pack, as they are not close to power outlets all day.
That all makes sense to me but doesn't make me switching off all the nice features of that great phone. It is not an a piece for exhibition in a shopping window, it is for my personal use for business and/or leisure activities. It even connects me via video when I am far away from home, it connects me to the social networks and it let me professionally do my work and up or download all info I need from my corporation. I can log in via VPN to my workplace and edit documents by collaborating with colleagues through the cloud. It shows me the way through the GPS, if I need.
It entertains me in many different way if I want, It helps me to find a good restaurant.
I do not longer use a notebook computer or a tablet.
My Notebook computer could work hardly 2 hours with the same usage like my SGN.
So, I accept that this racing machine does need after some laps a pit stop for filling up the power.
Just love that tool, just love it

These are the kinds of responses I was hoping people people would post rather than more whining about battery life. there are plenty of those threads already.
I was hoping for a POSITIVE thread people could read to calm their perceived issues with battery life. BTW I don't use BT head sets for Music. Yes another thing to deal with charging where you cannot simpy replace a battery. I prefer the far better quality wired earbuds.
